[image]Russian Kolka Glacier Collapses: Natural Hazards - NASA -- NASA Image Of The Day
On September 20, in the Caucasus Mountains, the collapse of a hanging glacier from the slope of Mt. Dzhimarai-Khokh onto the Kolka Glacier below triggered an avalanche of ice and debris. The debris slid more than 15 miles (24 km). The avalanche buried small villages in the Russian Republic of North Ossetia, killing dozens of people. The source of the avalanche can be seen at lower left, at the starting point of a long line of grayish avalanche debris standing out against the bright snow and ice...

Instead of detecting light in only 3—or even 30—wavelengths, it detects 220 distinct wavelengths of light. So many, in fact, that it observes a virtually continuous spectrum of light from .4 µm (blue) to 2.5 µm (mid-infrared).

On Sat., April 17, 2010, the Advanced Land Imager ALI instrument aboard NASA's Earth Observing-1 EO-1 spacecraft obtained this false-color infrared image of Iceland's Eyjafjallajökull volcano. A strong thermal source, denoted in red, is visible at the base of the Eyjafjallajökull plume. Above and to the right, strong thermal emission is also seen from the lava flows located at Fimmvorduhals between March 20 and April 13, 2010, where lava first reached the surface, generating impressive lava fo...

After exploring the South Pacific onboard the HMS the young Charles Darwin theorized that the beautiful, low sandy islands built on coral reefs had started as rocky volcanic peaks. His theory, still accepted today, holds that reefs build around the outer edge of volcanic islands. In warm, tropical waters, the reefs constantly grow, while the island subsides until only the low, sandy reef remains. Samples of types of South Pacific islands that fueled Darwin's theory are shown in this series of i...

Though the alert level has been dropped to Alert Level 2, scientists are still wary of the volcano, warning that it could still erupt with little or no warning. Changes in activity levels, possibly for the next few months, are to be expected says the United States Geological Survey (USGS) Cascades Volcano Observatory.Mou...
